DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Referring to FIGS. 1, 2, 3 and 4, a paperboard box according to the present invention basically is a piece of paperboard 10 and the paperboard 10 provides two opposite folding lines 13 in the middle area thereof and both ends of the respective folding line 13 extend a slant split line 11 to a lateral edge thereof respectively such that two opposite lower pieces 14 are formed and the respective lower piece 14 is trapezoid with an outer short base. Further, a first lateral piece 15 and a second lateral piece 16 are constituted next to the folding lines and the slant split lines 11. The lateral pieces 15, 16 at the long outer edges thereof are oppositely attached with a locating ear 17 respectively as shown in FIG. 1. An upper cover 20 as shown in FIG. 2 is unequal sided polygon with two opposite slits 21 corresponding the two locating ears 17.

[0021] At the very first, the split lines 11 can be split to separate the lower pieces 14 from the first lateral piece 15 and the second lateral piece 16 respectively while the paperboard box is in use. Then, both ends of the first lateral piece 15 are crossly overlapped to both ends of the second lateral piece 16 respectively and are fixedly attached to each other by means of the glue or the staple. Thus, the joined ends enclose the lower pieces 14 and are looked like both ends of a ship, that is, the paperboard 10 can be arranged to provide a ship like paperboard box with a hollow space therein as shown in FIG. 3 for receiving the food such as little octopus balls or the like. Finally, the upper cover 20 can be affixed to the hollow space in a way the slits 21 being pierced with the locating ears 17 on the paperboard 10 as shown in FIG. 4 such that it can prevent the foreign substance from entering the paperboard box and it is possible for the paperboard being piled one and another.

[0022] Referring to FIGS. 5, and 6, a second embodiment of the present invention is illustrated. The first and the second lateral pieces 15, 16 provide further split lines 19 respectively next to both ends thereof as shown in FIG. 5 such that both ends of the first lateral piece 15 can be fixedly attached to both ends of the second lateral piece 16 respectively in away of two adjacent ends thereof crossly overlapping each other as shown in FIG. 6. Hence, the paperboard 10 can form a ship like paperboard box with two ship ends.

[0023] Referring to FIGS. 7 and 8, a third embodiment of the present invention is illustrated. The first lateral piece 15 or the second lateral piece 16 at the long outer side thereof extends an upper cover 20 with a folding line 13 in between instead of one of the locating ear 17 so that the only locating ear 17 is possible to pierce a slit 21 on the upper cover 20 as soon as the ship like paperboard box is formed and the food is received therein as shown in FIG. 8. The upper cover 20 is extended from the second lateral piece 16 as shown in FIG. 7, and it is noted that the upper cover 20 can be extended from the first upper cover 15 instead of the second upper cover 16.

[0024] Referring to FIGS. 9, 10 and 11, a fourth embodiment of the present invention is illustrated. The locating ears 17 in FIG. FIG. 1 have been omitted in FIG. 9 and both of the lower pieces 14 extend outward beyond the short edges of the lateral pieces 15, 16. The upper cover 20 provides a plurality of split lines 22 at the periphery thereof to constitute a plurality of limit pieces 23 and two opposite slits 21 are disposed next to two opposite short edges as shown in FIG. 10. The two lower pieces 14 at the outer end parts thereof can pierce through the two slits 21 on the upper cover 20 and the limit pieces 23 are bent downward to fix the paperboard box of the present invention as soon as the split lines 22 after the ship like paperboard box is formed. Thus, a complete package of the paperboard box of the present invention can be formed advantageously.

[0025] Referring to FIGS. 12 and 13, a fifth embodiment is illustrated. An upper cover 20 extends outward from the second lateral piece 16 and a L-shaped hook ear 12 is attached to the first lateral piece 15 corresponding to the slit 21 on the upper cover 20 so that the hook ear 12 can pierce the slit 21 to lock the upper cover 20 as soon as the ship like paperboard box is formed and the food or the like is received therein. It is noted that it is possible to provide the upper cover being extended from the first lateral piece 15.

[0026] It is appreciated from the foregoing that the paperboard box of the present invention offers the following advantages:

[0027] 1. A ship like paperboard box can be made from a simple sheet of paperboard, which provides several split lines and folding lines so as to form folded pieces for being overlapped each other. The lovely ship like paperboard box can make the food such as the little octopus balls inside the box worthwhile and enhance the purchase desire of the consumer. Further, the paperboard box of the present invention can solve the problem of environment protection. In addition, it is possible for the paperboard box to be spread out so as to reduce the occupying space during being stored up or being piled up for decoration.

[0028] 2. The two lateral pieces at both corresponding ends thereof are overlapped each other respectively and fixed at the lower pieces respectively such that the locating ears may obtain outward expanding forces to fix the upper cover firmly.

[0029] 3. The paperboard box of the present invention can be provided with different combinations such as the box with a separate upper cover, the box without any upper cover, the box integral with an upper cover part and etc. to meet different needs of the consumers.
